The Journal of the Acoustical Society of America, 1996
Aeroacoustics has been introduced since the momentum equations of fluid were transformed into the equations of sound transmission by Lighthill. Although the transmission from a sound source can be analyzed, little attention has been paid to a source with unsteady motion.

Acrobatics at the insect scale: A durable, precise, and agile micro-aerial robot
Sci. RoboticsAerial insects are exceptionally agile and precise owing to their small size and fast neuromotor control. They perform impressive acrobatic maneuvers when evading predators, recovering from wind gust, or landing on moving objects.

Publisher Summary Actively flying insects achieve the highest metabolic rates known, and they do so in the fraction of a second required to shift from quiescence to flight. This chapter focuses on the various adaptations that make possible the high metabolic rates necessary for flight. Flight depends on the biochemical and mechanical work done by the

Advances in Science and Technology, 2008
A butterfly's fore- and hindwings act as one low aspect ratio wing. The variation in the feathering angle is not as large as that of other insects such as a dragonfly and a damselfly. A butterfly varies the lead-lag angle of the forewing and the angle between the thorax and the abdomen at take-off. This implies the possibility that the insect moves all

Annual Review of Fluid Mechanics, 2005
▪ Abstract “What force does an insect wing generate?” Finding answers to this enduring question is an essential step toward our understanding of interactions of moving objects with fluids that enable most living species such as insects, birds, and fish to travel efficiently and us to follow similar suit with sails, oars, and airfoils.

The Evolution of Insect Flight
1994Abstract This is the first book on this subject since J W S Pringle's classic Insect Flight was published in 1957. Much has been written since on applied and ecological aspects of flight, but consideration of the question of the origin of wings and flight has been largely confined to armchair speculation in a scattered literature.

Abstract In the evolution of the Oligoneoptera, the tendency towards improved flight predominated over the tendency to improve the locking of the folded wings. With the complete metamorphosis characteristic of these insects, the function of feeding is accomplished by a poorly mobile larva, while winged imagos retain the functions of the ...
